Cooperative Synchronization Techniques for UWB Wireless Networks

This paper proposes a novel cooperation technique to achieve symbol synchronization, in the context of UWB-IR (ultra-wideband impulse radio) wireless networks. Basically, a set of nodes in the network characterized by reciprocal line-of-sight (LOS) transmission links may join efforts during the symbol acquisition phase in order to improve performance, either in terms of average acquisition time or robustness vs. false alarms. In this paper, the proposed methods are tested under realistic channel model propagation, including multipath and in presence of multi-access interference (MAI).
